Callers of sock_sendmsg(), and similarly kernel_sendmsg(), in kernel
space may observe their value of msg_name change in cases where BPF
sendmsg hooks rewrite the send address. This has been confirmed to break
NFS mounts running in UDP mode and has the potential to break other
systems.
This patch:
1) Creates a new function called __sock_sendmsg() with same logic as the
old sock_sendmsg() function.
2) Replaces calls to sock_sendmsg() made by __sys_sendto() and
__sys_sendmsg() with __sock_sendmsg() to avoid an unnecessary copy,
as these system calls are already protected.
3) Modifies sock_sendmsg() so that it makes a copy of msg_name if
present before passing it down the stack to insulate callers from
changes to the send address.

do_execute_actions() function can be called recursively multiple
times while executing actions that require pipeline forking or
recirculations. It may also be re-entered multiple times if the packet
leaves openvswitch module and re-enters it through a different port.
Currently, there is a 256-byte array allocated on stack in this
function that is supposed to hold NSH header. Compilers tend to
pre-allocate that space right at the beginning of the function:
a88: 48 81 ec b0 01 00 00 sub $0x1b0,%rsp
NSH is not a very common protocol, but the space is allocated on every
recursive call or re-entry multiplying the wasted stack space.
Move the stack allocation to push_nsh() function that is only used
if NSH actions are actually present. push_nsh() is also a simple
function without a possibility for re-entry, so the stack is returned
right away.
With this change the preallocated space is reduced by 256 B per call:
b18: 48 81 ec b0 00 00 00 sub $0xb0,%rsp

Including the transhdrlen in length is a problem when the packet is
partially filled (e.g. something like send(MSG_MORE) happened previously)
when appending to an IPv4 or IPv6 packet as we don't want to repeat the
transport header or account for it twice. This can happen under some
circumstances, such as splicing into an L2TP socket.
The symptom observed is a warning in __ip6_append_data():
WARNING: CPU: 1 PID: 5042 at net/ipv6/ip6_output.c:1800 __ip6_append_data.isra.0+0x1be8/0x47f0 net/ipv6/ip6_output.c:1800
that occurs when MSG_SPLICE_PAGES is used to append more data to an already
partially occupied skbuff. The warning occurs when 'copy' is larger than
the amount of data in the message iterator. This is because the requested
length includes the transport header length when it shouldn't. This can be
triggered by, for example:
sfd = socket(AF_INET6, SOCK_DGRAM, IPPROTO_L2TP);
bind(sfd, ...); // ::1
connect(sfd, ...); // ::1 port 7
send(sfd, buffer, 4100, MSG_MORE);
sendfile(sfd, dfd, NULL, 1024);
Fix this by only adding transhdrlen into the length if the write queue is
empty in l2tp_ip6_sendmsg(), analogously to how UDP does things.
l2tp_ip_sendmsg() looks like it won't suffer from this problem as it builds
the UDP packet itself.

net_sched: sch_fq: round of improvements
For FQ tenth anniversary, it was time for making it faster.
The FQ part (as in Fair Queue) is rather expensive, because
we have to classify packets and store them in a per-flow structure,
and add this per-flow structure in a hash table. Then the RR lists
also add cache line misses.
Most fq qdisc are almost idle. Trying to share NIC bandwidth has
no benefits, thus the qdisc could behave like a FIFO.
This series brings a 5 % throughput increase in intensive
tcp_rr workload, and 13 % increase for (unpaced) UDP packets.
v2: removed an extra label (build bot).

FQ performs garbage collection at enqueue time, and only
if number of flows is above a given threshold, which
is hit after the qdisc has been used a bit.
Since an RB-tree traversal is needed to locate a flow,
it makes sense to perform gc all the time, to keep
rb-trees smaller.
This reduces by 50 % average storage costs in FQ,
and avoids 1 cache line miss at enqueue time when
fast path added in prior patch can not be used.

TCQ_F_CAN_BYPASS can be used by few qdiscs.
Idea is that if we queue a packet to an empty qdisc,
following dequeue() would pick it immediately.
FQ can not use the generic TCQ_F_CAN_BYPASS code,
because some additional checks need to be performed.
This patch adds a similar fast path to FQ.
Most of the time, qdisc is not throttled,
and many packets can avoid bringing/touching
at least four cache lines, and consuming 128bytes
of memory to store the state of a flow.
After this patch, netperf can send UDP packets about 13 % faster,
and pktgen goes 30 % faster (when FQ is in the way), on a fast NIC.
TCP traffic is also improved, thanks to a reduction of cache line misses.
I have measured a 5 % increase of throughput on a tcp_rr intensive workload.

Currently, when one fq qdisc has no more packets to send, it can still
have some flows stored in its RR lists (q->new_flows & q->old_flows)
This was a design choice, but what is a bit disturbing is that
the inactive_flows counter does not include the count of empty flows
in RR lists.
As next patch needs to know better if there are active flows,
this change makes inactive_flows exact.
Before the patch, following command on an empty qdisc could have returned:
lpaa17:~# tc -s -d qd sh dev eth1 | grep inactive
flows 1322 (inactive 1316 throttled 0)
flows 1330 (inactive 1325 throttled 0)
flows 1193 (inactive 1190 throttled 0)
flows 1208 (inactive 1202 throttled 0)
After the patch, we now have:

====================
Signed-off-by: David S. Miller <davem@davemloft.net>
While BPF allows to set icsk->->icsk_delack_max
and/or icsk->icsk_rto_min, we have an ip route
attribute (RTAX_RTO_MIN) to be able to tune rto_min,
but nothing to consequently adjust max delayed ack,
which vary from 40ms to 200 ms (TCP_DELACK_{MIN|MAX}).
This makes RTAX_RTO_MIN of almost no practical use,
unless customers are in big trouble.
Modern days datacenter communications want to set
rto_min to ~5 ms, and the max delayed ack one jiffie
smaller to avoid spurious retransmits.
After this patch, an "rto_min 5" route attribute will
effectively lower max delayed ack timers to 4 ms.
